DoS via crafted response

First in queue outside full restaurant. Parents waiting outside queue.

Table for 2 becomes available.

Waiter to me: Table for 2?

Me: No, 3.

Waiter to 4th person in queue: Table for 2?

4th person: Yes.

Waiter skipped the pair after me and brought the next pair in.

Me: This restaurant is vulnerable to denial-of-service via crafted response.
